How to change the background color of an Edit Box
http://www.codeproject.com/cpp/cppfaq10dec04-23jan05.asp
You can change the background color of an edit control in a dialog by handling the WM_CTLCOLOR message in the dialog
class MyDialog : public CDialog {
//...
COLORREF _BkgColor;
HBRUSH _BkgBrush;
};
BOOL MyDialog::OnInitDialog()
{
//...
_BkgColor = RGB(0,255,0);
_BkgBrush = ::CreateSolidBrush(_BkgColor);
}
HBRUSH MyDialog::OnCtlColor( CDC* pDC, CWnd* pWnd, UINT nCtlColor )
{
hbr = CDialog::OnCtlColor(pDC,pWnd,nCtlColor);
if (pWnd()->GetDlgCtrlId() == IDC_MY_EDIT_CONTROL) {
pDC->SetBkColor(_BkgColor);
hbr = _BkgBrush;
}
return hbr;
}
In the OnInitDialog() handler for the dialog, we initialize the background color value and create a brush in that color. The WM_CTLCOLOR handler is called OnCtlColor. The edit control for which we want to change the color has the resource ID IDC_MY_EDIT_CONTROL. We set the text background to our background color using SetBkColor(), and the overall background for the control by returning the brush we created.
